The exam evaluates scientific principles in biology, chemistry, and physics, covering topics such as the human excretory system, density, and thermal energy transfer. Key concepts include tectonic plate movement, molecular bonding, photosynthesis, and the role of plant minerals in growth. It emphasizes experimental design, data interpretation, and the analysis of sound waveforms and population dynamics. Practical applications include separating mixtures, chemical reactions, and the use of models to simulate natural phenomena like asteroid impacts.
